Amazon SES vs SendGrid

Reachkit makes a cold email tool, which is a different job from both of these. Every price on this page was checked in October 2026 on each vendor’s own pages.

My verdict: for a team already on AWS, Amazon SES does the same core job for a fraction of the price. SendGrid earns its higher bill when you want the extras packaged: a dedicated IP and validations in one plan, a newsletter product, and no AWS account to run. Both send app and opt-in email by API or SMTP, and both forbid cold outreach.

Pick Amazon SES if:

• Price per email decides it. 100,000 emails cost $10 on SES’s à la carte rate or $16 on Essentials, against $34.95 on SendGrid Essentials 100k.
• Your app already runs on AWS and someone can handle DNS records, IAM permissions and bounce notifications.
• You want your own IP without changing plans: a standard dedicated IP is $24.95 a month on à la carte.

Pick SendGrid if:

• You’d rather start on a 60-day trial with no card than file a production-access request with AWS.
• Marketing needs newsletters too. Marketing Campaigns adds an editor, contact storage and signup forms, billed separately from $15 a month.
• You want one plan that bundles a dedicated IP, automated warmup, 2,500 validations and up to 1,000 teammates: Pro, from $89.95.

Checked October 2026. Prices in USD, billed monthly, from each vendor’s own pages.

Amazon SES makes a new account earn production access, while SendGrid lets it send on a trial straight away, though it can still refuse or review an account.

Amazon SES: every new account starts in a sandbox, separately in each AWS region. In it you can only mail addresses and domains you’ve verified, at no more than 200 messages per 24 hours and 1 per second. To leave, you file a request covering your mail type and website, and tick a box saying you’ll only email people who explicitly asked for it and that you handle bounces and complaints. AWS promises an initial response within 96 hours. Every From and Return-Path identity must be verified too, and you publish the DNS records yourself.

SendGrid: the trial runs 60 days, capped at 100 emails daily, card not required; after it, a paid plan. Setup means SPF and DKIM records for domain authentication plus link branding (Pro adds reverse DNS), then your code calls the v3 Mail Send API or uses SMTP.

Neither is a sure thing. People on r/aws and AWS’s re:Post forum describe production requests that were turned down, including a 2026 re:Post question from a sender whose only recipient was their own inbox, refused twice despite a verified domain with DKIM. SendGrid refuses accounts too: in 2024, users on DigitalOcean’s and Bubble’s forums posted its email saying it was “unable to proceed with activating your account”. I’d file the SES request before writing any code.

Amazon SES and SendGrid both put new senders on shared IP pools; they differ in how you buy your own IP and how precisely they state the rules.

Amazon SES offers four routes. Shared IPs are the default. A standard dedicated IP costs $24.95 a month on à la carte. Managed dedicated IPs, which SES warms up and scales for you, cost $15 a month per account plus $0.08 per 1,000 emails on à la carte, and come included with Pro. You can also bring your own address range, from $6,387.20 a month. Virtual Deliverability Manager, SES’s deliverability reporting, is part of every plan and costs $0.07 per 1,000 on à la carte. Its global version adds inbox placement tests and blocklist monitoring: Pro includes a small allowance, and Essentials customers pay $1,250 a month for it.

SendGrid sends for trial and Essentials customers from shared groups of addresses. Moving to Pro gets you a dedicated IP that SendGrid warms automatically, with IP pooling, reverse DNS, and bounce and block classifications in reporting. Each further IP is $30 monthly, and the console lets you add one per month; Twilio recommends a minimum of two from roughly 200,000 to 300,000 sends a month.

AWS publishes its numbers: it advises keeping bounces below 2%, reviews an account at 5% bounces or 0.1% complaints, and may pause sending at 10% or 0.5%. Twilio’s Email Policy gives no numeric limits, and its acceptable use policy lets Twilio suspend an account that breaks the rules.

SendGrid bundles more daily tooling into its plans; Amazon SES gives you AWS parts to connect.

• Events. SES reports bounces and complaints by email or through Amazon SNS topics your app subscribes to. SendGrid pushes events to your app by webhook: 2 webhooks on Essentials, 5 on Pro.
• Activity search. SendGrid keeps 3 days of searchable activity on Essentials and 7 on Pro; longer history is sold at an unpublished price.
• Inbound mail. SES hands incoming mail to receiving rules or to Mail Manager, with processing at $0.15 per 1,000 on à la carte. With SendGrid, the Inbound Parse webhook forwards it to a URL in your app. There’s no reply inbox on either side.
• Address checks. SES Email Validation costs $0.01 an address on à la carte, and Pro includes 2,500 checks a month per region. SendGrid Pro includes 2,500 validations; Essentials includes none.
• Teams. SES access runs through AWS IAM permissions. SendGrid Essentials has one teammate, while Pro allows up to 1,000, with subusers and SSO.

Neither Amazon SES nor SendGrid writes email with AI, so the difference is what each offers developers and their AI assistants.

AWS publishes an amazon-ses skill that helps AI coding agents set up and troubleshoot SES sending. It’s served through the AWS MCP Server (MCP being how an assistant such as Claude Code plugs into an outside service), and AWS’s guide covers Claude Code, Codex, Cursor and Kiro. AWS notes the skill leaves out Mail Manager and receiving email.

SendGrid has no AI tools of its own, as a Twilio post from March 2026 put it. The MCP server Twilio offers is a public beta limited to reading: it looks things up in SendGrid’s documentation and support articles, and can’t send or change anything. Community SendGrid MCP servers exist.

For code, SES offers its v2 API, SMTP and the AWS SDKs; SendGrid offers its v3 REST API, SMTP, client libraries, scoped API keys and, on Pro, subusers.

Amazon SES is one service inside an AWS account, while SendGrid is a product you sign up for on its own, and most of their differences follow from that.

SES bills like the rest of AWS. Outbound mail is charged per recipient, so one message to three people counts three times. Plans apply per account and per region, so Pro’s $105 fee repeats in every region you send from, and other AWS charges such as data transfer can apply. Since July 21, 2026, accounts that are new or have sent nothing since June 1, 2025 begin on Essentials at $0.16 per 1,000, while active senders keep à la carte at $0.10, and any account can switch to à la carte. SES has no campaign editor; its one contact list per account lives in the API, for subscriptions and unsubscribes.

SendGrid sells products around the sending. Marketing Campaigns, a separate subscription from $15 a month (5,000 contacts, 15,000 sends), brings an editor, segments, signup forms and, on Advanced, automation. Twilio Email, live since May 2026 on the same infrastructure as SendGrid, bills $0.0013 per message and nothing monthly.

Read the comparison pages with care. Twilio’s own “SendGrid vs Amazon SES” page ranks for this search. It says SendGrid users needn’t “understand your compute charges” or “account for two message charges per email” for deliverability insights. If that means Virtual Deliverability Manager, it’s true of à la carte, but SES’s plans now include it. The page also claims “183+ billion emails every month”, where Twilio’s product page says 205 billion. Two third-party pages in the top ten still list SendGrid from $14.95; Twilio’s own page starts Essentials at $19.95.

Amazon SES costs less than SendGrid at every volume past SendGrid’s trial, with or without a dedicated IP, and the dollar gap grows with volume.

Assumptions: October 2026 list prices from AWS’s and Twilio’s public pricing pages, monthly billing, one AWS region, no attachments or tax. For SendGrid I took the lowest-cost route to each volume, overage included where it wins, at the per-email rates in Twilio’s 2025 pricing sheet. Twilio’s own advice is to upgrade rather than pay overages; Pro 1.5M covers a million emails for $799. SES Pro includes managed dedicated IPs, validations and some placement tests.

A second dedicated IP adds $30 on SendGrid and $24.95 on SES à la carte. Below about 15,000 emails a month, Twilio Email undercuts SendGrid Essentials ($13 at 10,000), though not SES. On free sending, AWS’s pages disagree: its July 2026 announcement closed the SES free tier to new customers, who get up to $200 in AWS credits, while the SES FAQ still offers 3,000 free messages a month for a year.

Amazon SES rates higher than SendGrid on G2 and Capterra. On Trustpilot, SendGrid scores poorly and SES has only a thin listing. Ratings as of October 2026:

Amazon SES: reviewers like the price and the reliability. “Affordable” and “Reliability” are among the most-tagged pros on G2, and one Capterra reviewer calls it “reliable, scalable, and affordable”. The complaints are about effort: another Capterra review says “Amazon SES is not beginner-friendly”, G2’s cons tags include difficult setup (8) and poor customer support (6), and denied production requests keep coming up on r/aws and AWS’s re:Post forum.

SendGrid: of the 45 Capterra reviews that bring up its API for developers, the site’s summary reads 89% as positive. Accounts and support draw the criticism. Capterra’s summary finds 53 reviews describing unpredictable account restrictions, 79% of them negative, and Trustpilot’s summary puts support first among complaints. A 2025 r/SaaS thread says “SendGrid’s only solution is to upgrade from $20 / month to $90 / month”, while a 2026 one still calls it sensible “between 10K-50K emails”.

This is our product, and it replaces neither tool, since Reachkit doesn’t send app or transactional email. It fits one reader: someone who came to SES or SendGrid hoping to email prospects who never signed up, which both forbid. That’s the job Reachkit does. Connect your Google, Microsoft or IMAP inboxes with no per-inbox fee, and mail goes out through each one’s own provider, not an email API. If you’d rather not touch DNS, Reachkit registers new domains for you at $15 a year each, builds inboxes on them for $5 a month each and starts AI warmup on every one. The Growth plan is $39 a month (October 2026), with 30 days free and no card. See Reachkit vs Instantly and Reachkit vs Smartlead for how it stacks up against other cold email senders.

Moving between Amazon SES and SendGrid is configuration work: your domain and suppression data come with you, while IPs, keys and history stay behind.

• Domain. Verify it on the new side and publish the new DKIM and SPF records next to the old ones before you move traffic.
• Going to SES. Request production access in each region you’ll send from, then check which price model the account landed on. A defaulted Essentials account can drop to à la carte immediately.
• Going to SendGrid. The trial’s 100 emails a day won’t carry production mail; budget for a paid plan.
• Suppressions. Take your bounce, complaint and unsubscribe lists across, so nobody who left hears from you again.
• Events and inbound. SendGrid’s event webhook maps to SES notifications through SNS, and Inbound Parse to SES receiving rules or Mail Manager. Both accept SMTP, so an app that sends over SMTP mostly changes host and credentials.
• Dedicated IPs don’t move. A new one starts with no reputation; SendGrid Pro and SES managed IPs warm up automatically.
• Billing. A SendGrid overage shows up a month later, and moving up a plan won’t wipe it. SES usage lands on your AWS bill.

My rule for this pair: if your app already lives in AWS, start on Amazon SES, move the account to à la carte unless the plan extras earn their keep, and request production access early. Neither SendGrid nor Twilio Email comes close to $10 for 100,000 emails. I’d pay for SendGrid when nobody wants to own the AWS plumbing, when marketing needs a newsletter editor too, or when Pro’s bundled IP, warmup, validations and seats save you building them. Either way, keep cold outreach off both.
